Problem with library(rpud) (GPU library)

I'm trying to install the rpud package in R to use my GPU

I'm getting this:

Error: package or namespace load failed for ‘rpud’ in inDL(x, as.logical(local), as.logical(now), ...): unable to load shared object 'C:/Users/eafpres/Documents/R/win-library/3.4/rpud/libs/x64/rpud.dll': LoadLibrary failure: The specified module could not be found.

the dll is in the path specified
lenovo Y50 touch, Windows 10
Installed latest Nvidia software for the GeForce GTX 860M
It says I have CUDA 8.0 installed
I was able to download and install packages rpud and rpudplus version 6.1 in RStudio everything seems OK until I actually try to load the library

Any help would be welcome
